"If your pH is low at dawn and high late in the day, and you have algae, the pH swings would be because of the algae. See overnight the algae uses up dissolved oxygen and gives off CO2 which when mixed with water acts as a weak acid but then…"

My well water is hard so that may be why, but its seems to be high out of no where. I tested around noon and it was 7.6, tested again at…"
Eric Warwick replied to Adam Garrett-Clark's discussion Natural ways to bring down PH" citric acidI've heard Sylvia uses pH down, but don't buy it for aquaponics, citric acid isn't safe for bacteria.

Jason Rampollo replied to Adam Garrett-Clark's discussion Natural ways to bring down PH"Does anyone know if General Hydroponics PH-down is safe to use to lower PH? I've heard that it is, but one of the ingredients is citric acid."
TCLynx replied to Adam Garrett-Clark's discussion Natural ways to bring down PH"In much of the country the cause of high pH is going to be the source water. HARD WATER! If you have hard water and you have to top up with it all the time, then your top up water can easily keep you pH over 7.5. Lets face it if…"
Jeremy Pickens replied to Adam Garrett-Clark's discussion Natural ways to bring down PH"Sorry guess I should have read back a few more pages. I agree plants do better in a more acidic environment. If you managed pH for plants then you would aim for 5.5 -6.5 if you managed your system for nitrifiers then you would aim for 7.5-8.5. That…"

I have right now or will have in the next couple weeks; tilapia, bluegill, red ear sunfish, green sunfish, Sacramento perch, Sacramento blackfish, channel cats, triploid carp, and trout. Send…"
Adam Garrett-Clark replied to Adam Garrett-Clark's discussion Natural ways to bring down PH"Great, thanks for all this everyone. Thats really good to hear Jon, that you've seen a lot of others with high PH. I do have tons of algae growth, I have three aquatic plants I put in for shelter for the fish as well. My pump constantly gets…"
Jon Parr replied to Adam Garrett-Clark's discussion Natural ways to bring down PH"Good info there, Jeremy. Adam mentioned his plants weren't growing at all a few hours ago. Good point about testing the means of testing pH. I have different results with pen, litmus, and reagents every time I compare them. I don't…"
Eric Warwick replied to Adam Garrett-Clark's discussion Natural ways to bring down PH" I'm going to answer what I think your first question was: If you have a high pH. or alkaline then it's harder to bring it down over time, because you have what a high pH. brings a system, high pH.

Jason Eaton replied to Adam Garrett-Clark's discussion Natural ways to bring down PH"Are you saying that if you have high alkaline water then the reagent methods of detecting ph maybe wrong? Or are you saying you could have media that renders the reagent tests inadequate?
Thanks."
Eric Warwick replied to Adam Garrett-Clark's discussion Natural ways to bring down PH"Here's an idea, add a CO2 bubbler and get Carbonic Acid, which should lower pH. However. this is the main indicator for someone growing weed (I have some pretty funny stories from my hydroponic store--which is 1/2 block from a cannabis…"
Jeremy Pickens replied to Adam Garrett-Clark's discussion Natural ways to bring down PH"That high of ph is not going to hurt fish and nitrifying bacteria perform well at that ph, however the fraction of unionized ammonia (NH3)can become very high. That is ok if the concentration of TAN (Total ammonia nitrogen ) is low. TAN is made up…"
Jon Parr replied to Adam Garrett-Clark's discussion Natural ways to bring down PH"I've not done it, but I've read that vinegar is a no-no for AP. I'm sure Eric is right, a mature biofilter can probably handle it, but if your water is 8.4 and you are probably wanting it somewhere in the mid 6's, then you…"
